CARPETING Filed Dec. 18, 1935 INVENTOR ATTORNEYJ Patented Dec. 7, 1937 UNITED STATES PATENT OFFICE 3 Claims.

My invention relates to carpeting or floor covering made up of a plurality of strips of carpet which when completed has the appearance of a broadloom carpet.

The primary object of my invention resides in the provision of means whereby a plurality of strips of carpets may be effectively sewed together to produce, in efiect, a broadloom carpet.

More specifically, it is an object of my invention to provide a novel construction at the longitudinal edges of the strips of carpet adapting the strips to be fastened together very securely and without objectionable appearance.

It is a further object of my invention to provide reenforcing pliant wires along the longitudinal edges of the strips of carpet adapted to cooperate with the means for attaching the strips together in a manner to provide a secure seam.

Another object is to provide a seam for carpeting of the above character which is reenforced by metal wire adapted to take a set.

How the foregoing objects and advantages, together with others which will appear to those skilled in the art, are attained will be more apparent from a consideration of the following description referring to the accompanying drawing, in which- Figure 1 is an enlarged cross-section through the seam portion or joint between two strips of carpet embodying my invention, and

Figure 2 is a diagrarmnatic bottom view of Figure 1.

In the drawing I have illustrated two strips of carpet 3 and 4 joined together at their longitudinal selvage edges 5. The strips of carpet may be of any standard width and of suitable lengths, and any number thereof may be secured together according to the width of the floor area to be covered.

I propose to secure the strips of carpet together by sewing and, in order to prevent the threads from pulling out at the edges and to ensure a very tight seam or joint, I provide reenforcement at the longitudinal edges. This reenforcement is accomplished by providing wires 6 in the backing fabric of the carpet, the wires being preferably made of soft, pliant, non-corrosive metal, i. e., a metal capable of readily taking a set. This facilitates cutting of the carpet, handling of it in rolls, and ensures that it will lie fiat on the fioor or, in the case of irregularities in the floor, it will readily conform to the floor condition. wire is such that the carpet may be readily cut, rolled, turned or otherwise handled, and come back to its proper position.

The wires 6 extend lengthwise of the carpet In other words, the nature of the and run as a warp with the warp threads 1 and are laid in between the weft threads 8 in the same manner as the stuffer threads 9 and become a permanent part of the backing fabric of the carpet.

The securing thread It] is confined to substantially the thickness of. the backing fabric so as not to sew in or disrupt the pile II or be exposed to view at the pile side of the carpet, i. e., the securing thread lies substantially within the plane of the backing fabric. The stitches are preferably passed directly in back of the wires 6 so as to embrace them as indicated at l2. As will be clear from inspection of Figure l, the wires 6 are closely adjacent to the longitudinal or selvage edges of the strips of carpet and, therefore, a relatively narrow stitch is employed and this without danger of the stitches pulling out because of their being anchored around the reenforcement wires. Thus the reenforcement wires constitute an anchorage or base on which the stitches may be tightly drawn without, however, distorting the longitudinal edge portions of the strips and further without causing openings in the pile. A very firm closed seam is, therefore, provided which, due to the stitches being confined to the thickness of the backing fabric, is concealed from view at the pile face of the carpet. Any form of stitch may be employed and the sewing may be done with the pile face of the strips toward each other so that, when the carpet is laid out fiat, the seam tightens to be practically unnoticeable.

I claim:

1. A floor covering comprising a plurality of strips of carpet, said strips having pliant wires adjacent their longitudinal edges extending with the warp, and means for securing said strips together comprising stitches embracing the adjacent wires of adjacent strips, said stitches being concealed by the pile of the carpet.

2. A floor covering comprising a plurality of strips of carpet having a fabric backing comprised of Warp, weft, and stufier threads, pliant wires in said backing extending in the direction of the warp and stufier threads and closely adjacent the longitudinal edges of the strips, and means for securing adjacent strips together at their adjacent edges comprising stitches embracing the wires.

3. A floor covering comprising a plurality of strips of carpet having a fabric backing comprised of warp and weft threads, pliant wires in said backing extending in the direction of the warp threads and between adjacent marginal warp threads, and means engaging said wires for securing said strips together.
